Protein name |
Potassium voltage-gated channel subfamily S member 1 |
Comment |
FUNCTION:Potassium channel subunit. Modulates channel activity and reduces the ion flow (By similarity).||SUBUNIT:Heteromultimer with KCNB1 and with KCNB2. Does not form homomultimers. Might also bind to other channel proteins (By similarity).||SUBCELLULAR LOCATION:Cell membrane; Multi-pass membrane protein. Note=May not reach the plasma membrane but remain in an intracellular compartment in the absence of KCNB1.||TISSUE SPECIFICITY:Detected in all tissues tested with the exception of skeletal muscle. Highly expressed in adult and fetal brain, fetal kidney and lung, and adult prostate and testis.||DOMAIN:The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.||SIMILARITY:Belongs to the potassium channel family. S (TC 1.A.1.2) subfamily. Kv9.1/KCNS1 sub-subfamily. |
